Don't take our word for it
Open your browser's developer tools, switch to the Network tab, and use any tool here. Your file never appears in it. That takes about thirty seconds and it settles the question better than a privacy policy can.
How this differs from the big tool sites
Smallpdf and iLovePDF are good software. Read their security pages, though, and notice what every promise on them is about: keeping your file safe once it is sitting on their servers.
they say
“256-bit TLS encryption for secure information transfer.”
Termiva
There is no transfer. The file is opened by your own device.
they say
“Your files are deleted from our servers after one hour.”
Termiva
Nothing to delete. No server ever held a copy.
they say
“ISO 27001 certified, GDPR compliant.”
Termiva
Those standards cover how a company handles your data. We never collect any.
they need
An internet connection, a queue, and an upload progress bar.
Termiva
Works in airplane mode once the page has loaded. Go and try it.
Where they are genuinely better: heavy conversion. PDF to Word, OCR on a difficult scan, and deep image compression are all things a server does better, and we would rather leave them out than do a weak imitation.
